Název v původním jazyce
ENA study of possible improvement in formulation design practices for optimized performance of Zn and Al pigmented epoxy coatings
Popis výsledku v původním jazyce
The effect of the ratio of the pigment volume concentration (PVC) to the critical pigment concentration (CPVC) belongs to well-known formulation design practices for optimized performance of pigmented organic coatings. The influence of this ratio in Zn an Al pigmented epoxy coatings on delamination kinetics of underlying steel has been investigated by electrochemical noise analysis (ENA) during 168 hrs immersion tests in 0.05 M NaCl. Two different Zn and Al pigmented epoxy coatings were prepared with different PVC/CPVC values but with the same vol. % Zn:Al ratio as well as with the same binder and hardener types applied. ENA was used to provide information about possible effect of PVC/CPVC values on delaminated corroding area time development in tested coating/steel systems. It has been concluded that in these systems it is recommended the use of certain low PVC/CVPC value in order to obtain high resistance to possible coating delamination from the metallic surface.
